The present invention relates to new and use ful improvements inclosures for containers, particularly collapsible tubes, and hasv forits primary object to provide, in a manner as herein- 5 after set forth,a device of this character which is adapted to be expeditiously mountedon the neck of the collapsible tube in lieu of the usual screw cap andwhich, after it has been so mounted, may be left thereon until all ofthe content has been used; after which the closure may be transferred toa full tube.

Another very important object of the invention is to provide a closureof the aforementioned character comprising a slidable valve of a novelconstruction and arrangement for controlling the discharge of the paste.cream or other material from the tube.

Other objects of the invention are to provide a. collapsible tubeclosure of the character described which will be comparatively simple inconstruction, strong, durable, highly efiicient and reliable in use,compact and which may be manufactured at low cost.

all of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawing whereinlike characters of reference designate corresponding parts throughoutthe several views,

and wherein:

Figure 1 is a top-plan view of a closure constructed in accordance withthe present invention, showing same mounted on a collapsible tube.

Figure 2 is a view in side elevation thereof.

Figure 3 is an end elevational view.

Referring now to the drawing in detail, it will be seen that theembodiment of the invention which has been illustrated comprises a platei of any suitable material, said plate being substantiallyrectangular inplan. While the lower face of the plate i is substantially flat, the topthereof is arcuate in cross section, as at 2.

The plate i has formed in the lower portion thereof a threaded socket 3for the reception of the usual neck 4 of a collapsible tube 55. Thus,the plate i is removably mounted on the tube E. Formed in the upperportion of the plate i is a discharge passage 6 which communicates withthe socket 3 for receiving paste, cream, etc., from the collapsible tube5.

Mounted for longitudinal movement on the top 2 of the plate i is aslidable'valve i of arcuate cross section, said valve also being'oi anysuitable material. The slidable valve i has formed therein a port 8 forregistry with the discharge passage 6 of the plate i.

Projecting from the ends of the slidable valve i are integral discsconstituting handles or the like 9 for actuating said slidable valve inoppo- 5 sitedirections. Formed longitudinally in the end portions of theslidable valve i are siots it. The slots iii accommodate screws it whichare mounted in the plate i and which slidably secure the valve 8thereon.

It is thought that the manner in which the closure functions will bereadily apparent from a consideration of the foregoing. With the valve 1in the position shown to advantage in Fig. 1 of the drawing, the port 8is out of registry with the discharge passage 6 and the collapsible tube5 is closed. When it is desired to open the collapsible tube 5, thevalve l is simply shifted longitudinally on the plate 9 in a manner tobring the port 8 into registry with the discharge passage 6. Theconstruction and arrangementv of the slots idand the screws ii is suchthat the movement of the slidable valve l toward open position will bearrested when the port 8 is in full registry with the discharge passageit. It will also be observed that the construction and arrangement issuch that one of the handles a projects beyond the corresponding end ofthe plate 8 when the valve l is in either open or closed position. Thus,the user knows that the desired movement of the valve i may be hadthrough the medium of the handle a which is projecting beyond or free ofthe plate i.

It is believed that the many advantages-of a collapsible tube closureconstructed in accordance with the present invention will be readilyunderstood although a preferred embodiment of the device is asillustrated and described, it is to be understood that changes in thedetails of construction and in the combination and arrangement of partsmay be resorted to which will fall within the scope of the invention asclaimed.

t is claimed is I l. A closure of the class described comprising a plateadapted to be threadedly mounted on a container and having a dischargepassage therein for communication with the container, said plateincluding a top or substantially arcuate cross section, a valve ofsubstantially arcuate cross section slidably mounted on the plate andhaving a port therein for communication with the discharge passage, saidvalve further having slots therein, headed elements mounted on the plateand engaged in the slots for slidably securing the valve on the plateand for limiting the movement of said valve in opposite directions onsaid plate, and integral operating handles projecting from opposite endsof the valve.

2. A closure of the class described comprising a substantiallyrectangular plate adapted tobe mounted on a containerand having adischarge passage therein for communication with the container, a valveslidably mounted on the plate and operable longitudinally thereon, saidvalve having a port therein for registry with the discharge passage inthe plate, means for slidably securing the valve to the plate and forlimiting the movement of said valve in opposite directions; and integralhandles projecting from the ends of the valve and constituting means foroperating same in opposite directions, the length of the valve andeither one of the handles being substantially equal to the length of theplate.

3. A closure of the class described compr sing a substantiallyrectangular plate having a threaded socket in the'lower portion thereoffor removably mountinggsaidplate on, the neck of a container, said plateincluding atop of substantially arcuate cross section having a dischargepassage therein communicating with the socket for receiving materialfrom the container, a substantially rectangular valve of arcuate crosssection mounted for longitudinal sliding movement on the plate, saidvalve having a port therein for registry with the discharge passage and.further having longitudinal slots therein, screws threadedly mounted onthe plate and engaged in the slots for slidably securing said valve andfor limiting the movement thereof in opposite directions on the plate,and integral operating handles projecting longitudinally from the endsof the valve, the length of the valve and either of the handlescorresponding to the length of the plate.
